To limit current flow — Resistors impede the flow of current, thus limiting it.

Ohm (?) — Resistance is measured in Ohms, named after Georg Ohm.

R = V / I — Ohm's Law states that R = V/I (Resistance = Voltage / Current).

Its physical size — Power rating, which determines the amount of heat the resistor can dissipate, is related to physical size.

It increases. — Resistors in series add up to create a larger total resistance.
